JOHN NATHAN, OF COUTOLENE, CALIFORNIA.

NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented Feb. 10,1914.

Application filed September 11, 1912. Serial No. 719,791.

To all tti/tom it may concern Be it known that I, Jol-IN NATHAN, a citizen of London, England, residing at Coutolene, in the county of Butte and State of California, have invented new and useful Improvements in Non-Refillable Bottles, of which the following is a specification.

My invention has relation to bottle-stoppers of that class wherein it is desirable to prevent the refilling of said bottles; and in such connection it relates particularly to the general construction and arrangement of non-refilling bottles.

The principal object of my invention is to provide an efficient, durable, and comparatively inexpensive stopper, which in position in the bottle cannot be removed and while permitting the discharge of the contents thereof yet efliciently preventing refillin of the bottle.

y invention, stated in general terms, consists of a non-removable bottle-stopper, constructed and arranged in substantially the manner hereinafter described and claimed.

The nature, characteristic features and scope of my invention will be more fully understood from the following description, taken in connection with the accompanying drawings forming part hereof, in which Figure 1 is a vertical central section of a bottle embodying features of my invention. Fig. 2 is a similar view with the valve removed, and Fig. 3 is a modification of the locking arms.

Like numerals designate corresponding parts throughout the several figures of the drawing.

Referring to the drawing, numeral 1 designates the neck of a bottle provided adjoining the lower end thereof with a circumferential groove 2, and the frusto-conically shaped reduced portion 3.

In the neck 1 of the bottle is fitted a hollow cylindrical stopper l having its lower end entirely open and top closed, said top being provided with a series of small openings 5 to permit of the discharge of the contents of the bottle. The lower end 6 of the stopper is reduced and shaped to conform with the formation of the reduced portion of the bottle neck. At intervals the side wall of the stopper is cut to form a series of spring arms 7, each of the arms being bent outwardly intermediate its free end and the body portion of the stopper, and then inwardly and downwardly to form the extension 8, which, when the stopper is pushed into position, seats itself in the groove 2, affordinga locking means for the stopper. The free ends of the arms 7 are then curved downwardly and slightly tapered as at 9 providing a stop and guide for the valve, which will be hereinafter described.

A series of baflie-plates, or disks 10 is soldered or fastened in any other well known manner to the interior of the stopper, each of the plates or disks being provided with a series of apertures 11, no two of the series being in registration with each other nor with the openings 5 in the stopper 4.

Before the stopper is inserted in the bottie neck, a frusto-conical valve 12, provided with the hollowed out part 13, is fitted in the neck so that it rests against the frustoconical reduced portion of the stopper when the bottle is in an upright or near vertical position.

Then the bottle is tipped for emptying, the valve 12 is unseated allowing the liquid to flow around it, and falls against the ends of the arms 7, which enter the hollowed part 13 and bear against the sides thereof acting as a guide to hold the valve in spaced position from the stopper so as not to interrupt the liow of the contents of the bottle.

In Fig. 3 a modification of the spring locking arms is shown, in which they are made of separate pieces soldered or fastened in any other well known manner to the side wall of the stopper, the upper end of the arm serving as a support for one of the baffie plates, while the others are fastened to the wall of the stopper. For this construction it is necessary to have openings 14: in the body of the stopper through which the extensions 8 pass in order to engage with the groove in the neck of the bottle.

Having now particularly described and ascertained the nature of my invention and in what manner the same is to be performed, l declare that what l claim is in a non-reiillable bottle, the combination with a neck having a groove, of a hollowcylindrical stopper mounted in said neck and provided with a Valve seat and valve Wardly and downwardly, so as to act as a guard, a. Valve mounted in said stopper, and guide and stop therefor. 13 spring arms Carried by said stopper, said In testimony whereof I ax my signature arms being bent at a point intermediate in presence of two Witnesses.
